Small solid litte red dot - Swampfox Sentinel 1x16mm Ultra Compact Micro Red Dot Sight

Solid little red do co witness well shake awake feature on the m is a real plus mounted it to a cr920 my only and main complaint is it won’t stay on the shot it 2x now and 2x it got loose and the processing of optic p. Took so long if not for that I might have given it a 5star and failed to mention the screws that came with it is garbage it’s too small or too thin.
